Mastering OpenCode - Code with an Open-Source AI Agent in Your Terminal: Plan, Build, and Run Local Models with the OpenCode Agentic Coding Tool

Master OpenCode, the open-source AI coding agent that runs in your terminal, editor, and desktop.

OpenCode puts a capable, model-agnostic coding agent right where you already work, with no vendor lock-in and no code sent to anyone’s servers. In this hands-on, project-based guide you’ll go from a fresh install to confidently steering OpenCode through real development tasks, using its Build and Plan agents, its permission system, and support for 75+ model providers including fully local models.

What you’ll learn:

• Install OpenCode and connect any provider, from OpenAI or Anthropic to a free built-in model
• Explore an unfamiliar codebase with /init, AGENTS.md, and fuzzy file search
• Switch between the Build and Plan agents to separate analysis from changes
• Configure the permission system in opencode.json to keep the agent safe
• Write clear agent instructions that keep outputs grounded and on task
• Apply a practical agentic workflow to a real coding challenge from start to finish
• Run local models for private, offline AI coding

Who this book is for:
Developers comfortable with basic coding and the terminal who want an open, flexible alternative to closed AI coding tools. No prior experience with agentic coding is required.

Why this book works:
This is a clear, step-by-step guide from the team at Zenva, whose courses have taught millions of people to code. Your download includes the starter assets and the complete project as a reference, so you can follow along and keep building with OpenCode afterward.
